JPs1986brat Posted September 7, 2015 Share Posted September 7, 2015 I own a 1986 Subaru brat and recently bought a 1987 turbo wagon for parts and motor swap. I can't find the pcm in the wagon or my brat. Can someone please help me? Link to comment Share on other sites More sharing options...
wagonist Posted September 7, 2015 Share Posted September 7, 2015 By PCM, I assume you mean Powertrain Control module. If so, they don't exist in these early models. The Legacy was the 1st model which controlled bot the engine & gearbox. The 87 has an ECU for the engine (which is mounted under the steering column on MPFI and turbo, and if it's got a flapper style MAF sensor, there is an ignition timing box mounted behind the dash between the glovebox & door (please correct me if I'm wrong, but that's where it is for RHD models). and if it's got a 4 spd auto, then the separate controller for that is in the left rear 3/4 panel. Other transmissions (including the 3spd auto) have no electronic control. Isn't a Brat carburettored? if so, why would it have any computer at all...
